HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 239,181, dated March22, 1881.

Application filed December 14, 1880 (No model.)

.To all whom it may concern:

Be it known that we, BENJAMIN F. MG- OARTY and RICHARD E. LINDSAY, bothof Scale, in the county of Russell and State of Alabama, have invented anew and useful Improvement in Horse-Powers, of which the followingis aspecification.

Figure 1, Sheet 1, is a plan view of the improvement, shown as appliedto the frame of a gin-house. Fig. 2, Sheet 1, is a side elevation. Fig.3, Sheet 2, is a side elevation of the frame that carries the gear-wheelshaft and drive-pulley. Fig. 4, Sheet 2, is an end elevation of theframe; and Fig. 5, Sheet 2, is a plan View of a part of the frame.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish horse-powers designedespecially for driving cotton-gins, but which can be used with advantagefor various other purposes, and which shall be so constructed that theycan be built upon the drive-wheels of ordinary horse-powers.

In the accompanying drawings, A. repre sents the posts of a frame of agin-house.

B are the beams, and O are the sleepers, that support the floor of thegin-room.

D is a block firmly beddedin the ground at the center of theground-floor.

To the block D is attached a step or socket, E, to receive the pivotformed upon or attached to the lower end of the shaft F, the upper endof which, or a pivot formed upon or attached to the said upper end,revolves in a hearin g, I), attached to the sleepers 0.

To the upper part of the shaft Fare attached radial arms G, which arestrengthened in position by the inclined braces H. The upper ends of thebraces H are attached to the outer parts of the arms G, and the lowerends of the said braces are attached to the shaft F.

To the upper sides of the outer ends of the arms G is attached a rim, I.

As thus far described the construction is the same as that of anordinary drive-wheel for a horse-power, except that the ordinarydrive-wheel has gear-teeth upon its rim.

To the shaft F, just above the arms G, are attached the inner ends ofasecond series of arms, J, of about twice the length of the said arms G.

The middle parts of the arms J rest upon the rim I, and their outerparts are strengthened by the inclined braces K. The upper ends of thebraces K are attached to the outer parts of the arms J, and the lowerends of the said braces are attached to the shaft F a little below thelower ends of the braces H.

To the upper side of the outer ends of the arms J is attached a rim, L,to the outer edge of which are attached toothed segments M, forming agear-wheel. By this construction a large and strong drive-wheel isproduced, which has the further advantage that it can be formed from anordinary drive-wheel by applying to the said ordinary wheel the longarms J, the long braces K, and thelarge rim L.

To the lower part of the shaft F are attached the inner ends of thesweeps N, to the outer ends of which the horses are attached.

To the shaft F, at a little distance from the inner ends of the sweepsN, are attached the inner ends of auxiliary sweeps O, which thus projectat an angle with the sweeps N. The

. outer ends of the sweeps N O are connected by a bar, P, as shown inFig, 1. With this construction the horses of each span are hitched tothe sweeps N O, the one in front of the other, so that both horses willtravel the same distance, and will thus do the same amount of work.

The teeth of the gearwvheel M mesh into the teeth of the smallgear-wheel Q placed upon the vertical shaft R. The teeth of thegearwheel Q are made about three times as long as the teeth of thesegments M, and the said gear-wheel Q is secured to the shaftRby keys orother suitable means, so that the gearwheel Q can be adjusted upon theshaft R to give at least three different bearing-places to receive wearfrom the teeth of the segments M. The gear-wheel Q can be reversed uponthe shaft It to expose the other sides of the teeth to wear. Thesegments M can also be detached and reversed to expose the other sidesof their teeth to wear. With this construction the gear-wheels M Q willlast much longer than gear-wheels constructed in the ordinary manner.The upper part of the shaft R revolves in bearings formed in or attachedto the top and bottom bars of an upright frame, S, the bottom bar ofwhich is secured to the sleepers O by bolts or other suitable means. Thelower end of the shaftR revolves in a step or socket attached to orformed in the cross-bar of the hanging frame or stirrup 5 T, the upperends of the side bars of which which are attached to the bottom bar ofthe frame S.

To the shaft R, between the bottom and top bars of the frame S, isattached a large pulley or band-wheel,U, around which passes a band,

V. The band V also passes around the pulley W of the gin or othermachinery to be driven. The band V also passes around a pulley orroller, X, to guide the said band into I 5 proper position to pass tothe pulley W. The

guide-pulley X is pivoted to the top and bottom bars of a frame or sash,Y. The top and bottom bars of the sash Y rest in notches in the adjacentsides of the arms Z attached to the bottom and top bars of the frame S.The notches in the arms Z are made longer than the thickness of the sashY, and the said sash is secured in place by wedges a driven into thesaid notches along the top and bottom bars of the said sash Y, sothatthe sash Y,

and with it the guide-pulley X, can be adjusted as the relativepositions of the pulley U W may require, to cause the band V to run'even and smooth.

Having thus described our invention, we 0 claim as new and desire tosecure by Letters Patent- 1. The combination, with the shaft F, of thearms G, braces H K, rim I, arms J, rim L, and toothed segments M, asshown and described, 3 5 to form an attachment applicable to thedriving-wheel of cotton-gin horse-powers.

2. In a horse-power, the combination, with the upright frame S, thatcarries the shaft R, and the sash Y, that carries the guide-pulley 40 X,of the arms Z, having notches upon their adjacent sides, and the wedgesa, substantially as herein shown and described, whereby the guide-pulleycan be adjusted as the direction of the band may require, as set forth.
